Resumo
Responsible for the removal of material from the train wagons and accommodation on conveyors belts, the Rotary Car Dumper is an essential equipment for handling bulk materials, and its stop by failure or even scheduled maintenance generates production losses. This paper proposes an improvement in the maintenance process of trunnions, responsible for dumper support, through structural modifications, in order to reduce the current 10 hours of production downtime to replacement the equalizing wheels. To this end, the proposed structure was modeled and characterized in SolidWorks software, and simulated using the Finite Element Method. Static and fatigue tests were performed according to the European Federation of Maintenance. Simulation results indicate that the change is feasible technically meeting the safety standards required by the FEM and its installation will not affect useful life of the system.
